Traditional cementing procedures for repairing or abandoning oil and gas wells that leak GHG emissions are unreliable. The chemical and physical properties and processes that attend the setting of cement and the long term deteriorating effects of reservoir fluids that come in contact with it, make cement a less idea solution for sealing wells.

Seal Well is advancing its proprietary well sealing technology that is set to address these issues. The company has developed proprietary plugs and procedures that are more effective, reliable, and less expensive than cement.

Results from this ERA-funded demonstration project indicate that permanent sealing of GHG emitting wells, including those that penetrate CO2 sequestration reservoirs, can be reliably and economically accomplished by using a low melting point bismuth alloy molded in situ.
